Add serial# for SPL SDP download
After update this, uuu(>1.6) can use below command to filter out devices
when multi boards connected.
uuu -ms <serial#> ...
[sudo] uuu -lsusb can list known devices with serial# informaiton.
Serial number is retrieved via get_board_serial() and passed to
g_dnl_set_serialnumber(). This part is conditionally compiled for i.MX94
only now.
